Abstract
With the rapid development of information technology, the importance of distributed file systems in data storage and sharing has become increasingly prominent. However, traditional distributed file systems face challenges in terms of data security, privacy protection, and trust mechanisms. To address these issues, this study investigates the application potential of blockchain technology in distributed file systems, aiming to construct an efficient, secure, and trustworthy distributed file storage architecture. By analyzing the core characteristics of blockchain technology, such as decentralization, immutability, and smart contract functionality, and integrating them with the practical requirements of distributed file systems, a blockchain-based distributed file system model is proposed. This model utilizes blockchain to record file me tadata and access permissions, ensuring data integrity and traceability, while leveraging smart contracts for automated management, thereby enhancing system reliability and efficiency. Experimental results demonstrate that the proposed model exhibits significant advantages in terms of data storage security, flexibility of access control, and stability of system performance. Additionally, this study designs an optimized data sharding and redundant storage strategy, effectively reducing storage costs and improving data availability. The primary innovation of this research lies in the deep integration of blockchain technology with distributed file systems, proposing a solution that combines security and efficiency, offering new insights for the future development of distributed storage technologies. The final conclusion indicates that blockchain technology can significantly enhance the functional characteristics of distributed file systems, possessing important theoretical value and broad application prospects.
